An electromechanical path to vehicle stability
2017 - PACE Award Winner
What: Electromechanical Active Roll Stabilizer
Innovation: Schaeffler's electromechanical approach to active roll control ensures that a vehicle does not tilt sideways when cornering at high speeds, resulting in greater driving comfort and stability.
First Customer: BMW
Judge's Citation: Traditionally, RIDE and HANDLING are viewed as a tug-of-war where vehicle engineers trade-off one to get the other. To provide stability, engineers use roll stabilizers (AKA: Anti-Sway Bar) to increase vehicle stiffness and mitigate the tipping sensation in turns but this results in a harsh ride over rough roads. Hydraulic anti-sway bar disconnect systems appeared several years ago, but their sluggish response times and high vehicle lifecycle costs effectively limited their application to SUVs and other high CG vehicles. Schaeffler's electromechanical roll stability solution eliminates hydraulics, and by offering both 12v/48v options brings the ride and comfort advantages of an anti-sway bar disconnect system to a wide range of performance, luxury and mainstream vehicles.
Launched on the 2016 BMW 7-Series, Schaeffler's electromechanical Active Roll Stabilizer ("eARS") has been adopted as a new standard for multiple brands spanning ultra-luxury, high performance, and hybrid vehicle programs. eARS modular architecture, tunable elastomeric coupler, internally developed touch-less torque sensor, and 12v/48v capabilities afford OEMs the ability to minimize application engineering timing/costs for bringing Mode Decoupling to a broader array of vehicles. eARS marks Schaeffler's expansion from its traditional metal forming foundation, showcasing new competencies in electronics, software development, software application engineering/validation/lifecycle management, placing the company squarely in the realm of mechatronic innovation.
